Designing with Vision

This week I caught a talk by Philip Haine from Obvious Design about Designing with Vision. Philip outlined how some products that seem to ignore the "best practices" of design turn out to be breakthroughs, while others that are designed by the book suffer from mediocrity. He also addressed why product design processes often suffer from have radically shifting requirements. According to Philip the answers lie in understanding product vision:

Product vision is the missing discipline (marketing, design, development, etc.) in the product creation process. It has a profound effect on the outcome, is a source of innovation, and can override design quality.
